Ripple resistance is suitable for: elevator, crane, rolling mill, wire drawing machine, centrifuge, load test, etc.
WDLK series filter reactors are used in low-voltage filter cabinets in series with filter capacitors. Tune to a certain resonant frequency. Used to absorb harmonic currents of corresponding frequency in the power grid. There are a large number of harmonic sources such as rectifiers, converters, and frequency conversion devices in low-voltage power grids, and the higher harmonics they generate will seriously endanger the safe operation of the main transformer and other electrical equipment in the system. After the filter reactor and the capacitor are connected in series, it not only can absorb the harmonics of the power grid to a limited extent, but also improves the power factor of the system, which plays a greater role in the safe operation of the system.
The iron core is made of high-quality silicon steel sheet. The core post is divided into uniform small pieces by multiple air gaps. The air gap uses high temperature and high-strength adhesive to tightly adhere each small section of the core post to the upper and lower iron yokes
The core surface adopts special F or H class insulation paint, which greatly improves the reliability of long-term operation
The specific temperature of the product is low, the loss is small, the comprehensive utilization rate is high, and it is easy to install.
